The purpose of the multiple key agreement protocol is to get efficiency in computational and communicational aspects compared to multiple executions of single key agreement protocol. However ID based tripartite multiple key agreement protocols have been proposed, it is reported that they can not resist unknown key-share attack or impersonation attack. How to design a secure and efficient ID-based authenticated tripartite multiple key agreement scheme to prevent all kinds of attacks remains an open problem. This paper proposes a multiple key agreement scheme combing the existing single key agreement protocol with a key derivation function. The proposed scheme can not only increase computational efficiency compared to the existing multiple key agreement protocol, but can ensure security of the proposed schemes by using a security proofed single key agreement protocol and key derivation function.

Multi-modal techniques have received increasing interest in the neuroscientific and brain computer interface (BCI) communities in recent times. Two aspects of multi-modal imaging for BCI will be reviewed. First, the use of recordings of multiple subjects to help find subject-independent BCI classifiers is considered. Then, multi-modal neuroimaging methods involving combined electroencephalogram and near-infrared spectroscopy measurements are discussed, which can help achieve enhanced and robust BCI performance.

The present study developed teaching-learning activities to improve personal intelligences and to investigate their effectiveness. Significant differences were found in both interpersonal and intrapersonal intelligence. Positive effects appeared in cooperative attitudes, capacity to care for and understand others, and in reflective thinking abilities. The results suggest the importance of a balanced educational curriculum in order to enhance human affective aspects, self-esteem, cooperative classroom climate formation and the moral and character development of students. Consistent and systematic investigation is needed on multiple intelligences theory, development of teaching-learning activities, their longitudinal effects, and a fair assessment instrument.

There has been a discussion about housing classes in sociology and cultural geography since Rex and Moore`s study that housing classes are existing according to home ownership. Besides social classes. housing classes as a variable which explains life styles are existing. The study of housing classes needs microsociological approach which includes multiple aspects of resident`s social class, family type, home ownership, residential area.

This paper investigates the nature of Japanese argument cluster (Steedman 2000b). Based on Combinatory Categorial Grammar, a type-raising analysis of case particles which captures some aspects of the information structure in Japanese is discussed, including contrastive interpretation of coordination, wh-constructions, and some theme and rheme-related grammatical phenomena. These observations offer further support for the study of syntax, semantics, and phonology interface and the earlier analysis of English information structure.

Information culture is a concept with multiple and sometimes conflicting definitions. Nevertheless at a time when social and cognitive aspects of information and communication systems are recognized as being of similar significance as the technological functionality, the concept of information culture is demonstrating considerable value. This paper explains the concept of information culture and considers its value from two main perspectives: firstly as providing an analytical tool, and secondly as a means of providing practitioners with insight and sensitivity to the organisational contexts of their workplaces.

The purpose of this study was to investigate the influence of cooking wine's functions on food quality attributes. factor analysis, reliability analysis (Cronbach's $\alpha$), and multiple regression analysis were employed to analyze the data. The cooking wine functions were divided into 3 factors (expectation of utility, functionality, and quality enhancement). According to the multiple regression analysis of cooking wine factors to food quality, all factors had positive influences on food quality. Among the three factors, expectation of utility(=.556, p<0.001) had the most significant influence on food quality. And functionality (=.321, p<0.001) and quality enhancement(=.296, p<=0.001) also had significant effects in that order. further research should be conducted on cooking wine's utility aspects and their effects on food quality. Finally, we anticipate that the results of this study will be useful information for food-service companies.

During the last decade many researches have been working on multiple target tracking problem in the area of radar application, Various approaches have been proposed to solve the tracking problem and the concept of sensor fusion was established as an effort. In this paper utilization of geographic information for ground target tracking is investigated and performance comparison with the results of applying sensor fusion is described. Geographic information is used in three aspects: association masking target measurement and re-striction of removing true target. Simulation results indicate that using two sensors shows better performance with respect to tracking but a single with geographic information is a winner in reducing the number of false tracks.

Renal cell carcinoma is the third most common metastatic tumor to the bone and soft tissues of the head and neck. The common sites of metastatic renal cell carcinoma in head and neck region are nasal cavity, paranasal sinuses, oral mucosa, gingiva, tongue, palate, lip as the favored site. The present paper deals with one patient with metachronous oral tongue, nasal cavity and suspicious brain metastases after 2 years of renal cell carcinoma nephrectomy. Also, the patient had history of total thyroidectomy for thyroid follicular carcinoma. Total excision of nasal cavity and tongue mass were performed. Therapeutic aspects are briefly reviewed in literature.

Superconducting joints between Bi-2223/Ag tapes are fabricated by a press & reaction anneal and a multiple press & anneal. The silver sheath was mechanically or chemically removed from one side of each tape without altering the superconducting core. The exposed superconducting core of the two tapes were brought into contact and pressed so as to form a lap joint. The joined tapes were then subjected to a series of different thermomechanical treatments to achieve optimum heat treatment condition. The result from transport measurements shows that critical current ($I_c$) transmitting through joined area reaches 9A, approximately 60% of the current capacity of the tapes themselves. The critical current through joined area was improved by repeated press and reaction annealing. Measurements of the current-voltage relationship were made with several configuration of the voltage probes to characterize the critical current variation and I-V curve along the joint. Also discussed are microstructural aspects of the superconducting joint.
